A statewide, population-based time-series analysis of the increasing frequency of nonoperative management of abdominal solid organ injury.

Emergency operative intervention has been one of the cornerstones of the care of the injured patient. Over the past several years, nonoperative management has increasing been recommended for the care of selected blunt abdominal solid organ injuries. The purpose of this study was to utilize a large statewide, population-based data set to perform a time-series analysis of the practice of physicians caring for blunt solid organ injury of the abdomen. The study was designed to assess the changing frequency and the outcomes of operative and nonoperative treatments for blunt hepatic and splenic injuries. METHODS: Data were obtained from the state hospital discharge data base, which tracks information on all hospitalized patients from each of the 157 hospitals in the state of North Carolina. All trauma patients who had sustained injury to a solid abdominal organ (kidney, liver, or spleen) were selected for initial analysis. RESULTS: During the 5 years of the study, 210,256 trauma patients were admitted to the state's hospitals (42,051 +/- 7802 per year). The frequency of nonoperative interventions for hepatic and splenic injuries increased over the period studied. The frequency of nonoperative management of hepatic injuries increased from 55% in 1988 to 79% in 1992 in patients with hepatic injuries and from 34% to 46% in patients with splenic injuries. The rate of nonoperative management of hepatic injuries increased from 54% to 64% in nontrauma centers compared with an increase from 56% to 74% in trauma centers (p = 0.01). In patients with splenic injuries, the rate of nonoperative management increased from 35% to 44% in nontrauma centers compared with an increase from 33% to 49% in trauma centers (p < 0.05). The rate of nonoperative management was associated with the organ injury severity, ranging from 90% for minor injuries to 19%-40% for severe injuries. Finally, in an attempt to compare blood use in operatively and nonoperatively treated patients, the total charges for blood were compared in the two groups. When compared, based on organ injury severity, the total blood used, as measured by charges, was lower for nonoperatively treated patients. CONCLUSIONS: This large, statewide, population-based time-series analysis shows that the management of blunt injury of solid abdominal organs has changed over time. The incidence of nonoperative management for both hepatic and splenic injuries has increased. The study indicates that the rates of nonoperative management vary in relation to the severity of the organ injury. The rates increase in nonoperative management were greater in trauma centers than in nontrauma centers. These findings are consistent with the hypothesis that this newer approach to the care of blunt injury of solid abdominal organs is being led by the state's trauma centers.     

Operative blunt duodenal injury in children: a multi-institutional review

Background/AimOperative blunt duodenal injury in children is rare. The purpose of this analysis is to describe the clinical presentation, current management, and outcome of children with operative blunt duodenal injury.MethodsThe American Pediatric Surgical Association Trauma Committee solicited data from its members on children with blunt intestinal injuries identified at autopsy or operation from January 2002 through August 2006.ResultsFifty-four children from 16 hospitals with operative blunt duodenal injuries were identified: 0.67 patients per hospital per year. The most common mechanisms of injury were motor vehicle crashes (35%), bicycle crashes (22%), and nonaccidental trauma (20%). Forty-nine patients (90%) had positive physical examination findings on initial presentation, including peritonitis in 18 patients (33%). Twenty-five computed tomographic (CT) scans performed demonstrated free fluid, and 13 (52%), free air. Eleven CT scans used enteral contrast, and only 2 (18%) showed extravasation. Fifty-two patients (96%) survived to operation. The overall complication rate was 42%.ConclusionOperative blunt duodenal injury occurs less than once per year in the typical pediatric trauma center. Most of the patients have pertinent physical examination findings on arrival. Computed tomographic scans with enteral contrast do not seem to be helpful in diagnosis of duodenal injuries. Postoperative complications are frequent, but most children survive.     

Updated APSA Guidelines for the Management of Blunt Liver and Spleen Injuries

BackgroundNon-operative management of blunt liver and spleen injuries was championed initially in children with the first management guideline published in 2000 by the American Pediatric Surgical Association (APSA). Multiple articles have expanded on the original guidelines and additional therapy has been investigated to improve care for these patients. Based on a literature review and current consensus, the management guidelines for the treatment of blunt liver and spleen injuries are presented.MethodsA recent literature review by the APSA Outcomes committee [2] was utilized as the basis for the guideline recommendations. A task force was assembled from the APSA Committee on Trauma to review the original guidelines, the literature reported by the Outcomes Committee and then to develop an easy to implement guideline.ResultsThe updated guidelines for the management of blunt liver and spleen injuries are divided into 4 sections: Admission, Procedures, Set Free and Aftercare. Admission to the intensive care unit is based on abnormal vital signs after resuscitation with stable patients admitted to the ward with minimal restrictions. Procedure recommendations include transfusions for low hemoglobin (<7 mg/dL) or signs of ongoing bleeding. Angioembolization and operative exploration is limited to those patients with clinical signs of continued bleeding after resuscitation. Discharge is based on clinical condition and not grade of injury. Activity restrictions remain the same while follow-up imaging is only indicated for symptomatic patients.ConclusionThe updated APSA guidelines for the management of blunt liver and spleen injuries present an easy-to-follow management strategy for children.Level of EvidenceLevel 5.     

Clinical practice guidelines (CPGs) reduce costs in the management of isolated splenic injuries at pediatric trauma centers

Purpose

The American Pediatric Surgical Association Trauma Committee proposed the use of a clinical practice guideline (CPG) for the non-operative management of isolated splenic injuries in 1998. An analysis was conducted to determine the financial impact of CPGs on the management of these injuries.

Methods

The Pediatric Health Information System database, which contains data from 44 children's hospitals, was used to identify children who sustained a graded isolated splenic injury between June 2005 and June 2010. Demographics, length of stay (LOS), readmission rates, and laboratory, imaging, procedural, and total cost data were determined for all hospitals verified as a pediatric trauma center by the American College of Surgeons and/or designated by their local authority. Comparisons were made between facilities self-identifying as having a splenic injury management CPG and those without a CPG.

Results

Children (1,154) with isolated splenic injuries (grades 1–4) were cared for in 26 pediatric trauma centers: 20 with a CPG and 6 without (non-CPG). Median costs were significantly lower at CPG than non-CPG centers for imaging (US $163 vs. US $641, P?<?.001), laboratory (US $629 vs. US $1,044, P?<?.001), and total hospital stay (US $9,868 vs. US $10,830, P?<?.001). The median LOS for CPG and non-CPG centers were similar (3 vs. 2 days, P?=?.38), as were readmission rates within 90 days (3.1 vs. 5.1 %, P?=?.21). Multiple linear regression indicated that LOS (P?<?.001) and utilization of a CPG (P?=?.007) are significant independent predictors of total cost.

Conclusions

Utilization of a CPG to manage children with isolated splenic injuries at a pediatric trauma center results in significantly reduced imaging, laboratory, and total hospital costs independent of patient age, gender, grade, and LOS.     

Throwing out the "grade" book: management of isolated spleen and liver injury based on hemodynamic status

Purpose

Current organizational guidelines for the management of isolated spleen and liver injuries are based on injury grade. We propose that management based on hemodynamic status is safe in children and results in decreased length of stay (LOS) and resource use compared to current grade-based guidelines.

Methods

Patients with spleen or liver injuries for a 5-year period were identified using our institutional trauma registry. All patients were managed using a pathway based on hemodynamic status. Charts were reviewed for demographics, mechanism, hematrocrit values, transfusion requirement, imaging, injury grade, LOS, and outcome. Exclusion criteria included penetrating mechanism, associated injuries altering LOS or ambulation status, combined spleen/liver injury, initial operative management or death. Statistical comparison was performed using Student's t test; P < .05 is significant.

Results

One hundred one patients (50 spleen, 51 liver) meeting inclusion criteria were identified. Average actual LOS for all patients was 1.9 days vs 3.2 projected days based on American Pediatric Surgical Association guidelines (P < .0001). Actual vs projected LOS for grades III to V was 2.5 vs 4.3 days (P < .0001). All patients returned to full activity without complication.

Conclusions

Isolated blunt spleen and liver injuries, regardless of grade, can be safely managed using a pathway based on hemodynamic status, resulting in decreased LOS and resource use compared to current guidelines.     

Management of adult blunt splenic injuries: comparison between level I and level II trauma centers

BACKGROUND: The factors important in determining outcome when managing adult blunt splenic injuries continue to be debated. Whether trauma center level designation (Level I versus Level II) affects patient management has not been evaluated. STUDY DESIGN: We conducted a retrospective analysis of prospectively gathered data from the Pennsylvania Trauma Outcome Study database that collected information from 27 statewide trauma centers (Level I [15], Level II [17]). Adult patients (ages > or = 16 years) with blunt splenic injuries (ICD-9-CM 865) were evaluated. Demographic data, injury data, and trauma center level designation were collected, and patient management, length of stay, and mortality were analyzed. RESULTS: There were 2,138 adult patients who suffered blunt splenic injuries during the study period (1998-2000). Patients treated at Level II trauma centers (n = 772) had a higher rate of operative treatment (38.2% versus 30.7%) (p < 0.001), but a shorter mean length of stay (10.1 +/- 0.4 versus 12.0 +/- 0.4 days) (p < 0.01) compared with patients in Level I trauma centers (n = 1,366). The rate of failure of nonoperative treatment was lower at Level II trauma centers (13.0% versus 17.6%) (p < 0.05), but the mortality for patients managed nonoperatively was higher (8.4% versus 4.5%) (p < 0.05). Splenorrhaphy was performed more frequently in Level I trauma centers. CONCLUSIONS: Management differences exist in the treatment of adult blunt splenic injuries between institutions of different trauma center level designation. Multicenter studies should account for this finding in design and implementation.     

Differences in trauma care among pediatric and nonpediatric trauma centers.

To characterize pediatric trauma care, state trauma registry data from all designated trauma centers in Pennsylvania were divided into three categories, that from: (1) pediatric centers, (2) urban nonpediatric centers, (3) and rural nonpediatric centers. From October 1, 1986 through September 30, 1989 (3 years), 4,615 patients less than 15 years old were admitted to 28 trauma centers in Pennsylvania. Nonpediatric centers cared for the majority of children (2,734, 59.2%), but the average number of children treated per nonpediatric institution (105.1 per year) was far fewer than the average treated in the pediatric centers (940.5). Pediatric trauma centers in the state treated a younger population (6.4 +/- 4.2 years, mean +/- SD) compared with urban and rural nonpediatric centers (8.4 +/- 4.2 and 8.1 +/- 4.3 years, respectively; P less than .05). Pediatric centers received proportionately more children by transfer (56.2%), victims of falls (34.6%), pedestrian injuries (16.8%), and head and neck injuries (41.8%, all P less than .05). Nonpediatric centers received children directly from the scene of injury more frequently than transferred from other hospitals. The male:female sex ratio in urban nonpediatric centers was significantly higher (70.1%, P less than .05) than in the other two groups. Rural nonpediatric centers cared for a higher proportion of motor vehicle passengers (28.5%) and patients classified as "other" in the state registry, a category to which bicycle injuries are assigned (28.2%, P less than .05). Mortality was highest in rural nonpediatric centers (6.2%). The death rate in pediatric centers and urban nonpediatric centers were similar (4.1%) and significantly lower (P less than .05).(ABSTRACT TRUNCATED AT 250 WORDS)     

Use of a state-wide administrative database in assessing a regional trauma system: the New York City experience

BACKGROUND: A successful regional trauma care system should concentrate severely injured patients within trauma centers, and should improve severity-adjusted outcomes. We compared injured patients' outcomes in New York City's level 1 trauma centers and nontrauma centers. STUDY DESIGN: We analyzed 1998-2000 New York Statewide Planning and Cooperative Research System (SPARCS) data for 103,725 adult discharges from 70 New York City hospitals (15 level I trauma centers), using ICD-9CM codes 800-950. Their 227 DRG's were aggregated into 7 clinical injury classes. A severity index was extracted from each refined DRG, and deaths, age, and gender were analyzed. Regression analysis predicted death from age, gender, severity index, and trauma center discharge, with separate analyses of the three largest clinical classes, and estimated excess mortality because of trauma center discharge. RESULTS: Level 1 trauma centers discharged 48.2% of injured patients, with higher mean annual discharges per hospital (1,046 discharges per TC vs. 437 per NTC, p < 0.001). Trauma centers discharged more than half the central nervous system, general/gastrointestinal, cardiothoracic, and vascular injuries. Trauma center patients were 12.5 years younger than NTC patients (p < 0.0005), and were disproportionately men (64.7% TC vs. 47.2% NTC, p < 0.0005). For the entire patient cohort, and for central nervous system, orthopaedic and general/gastrointestinal injuries, severity, age, and gender adjusted mortality risk was significantly greater at trauma centers than nontrauma centers. CONCLUSIONS: New York City's trauma system concentrates injured patients in trauma centers on the basis of injury class rather than severity, but does not produce improved adjusted mortality outcomes for injured patients.     

Radiologic Evaluation of Pediatric Blunt Renal Trauma in Patients with Microscopic Hematuria

As a result of the rapid increase in medical costs, the efficacy of diagnostic imaging is under examination, and efforts have been made to identify patients who may safely be spared radiographic imaging. We reviewed the records of children who presented to our institution with suspected blunt renal injuries to determine if radiographic evaluation is necessary in children with microscopic hematuria and blunt renal trauma. We retrospectively reviewed the medical records of 1200 children (ages less than 18 years) who sustained blunt abdominal trauma and who presented to our level I pediatric trauma center between 1995 and 1997. Urinalysis was performed in 299 patients (25%). Urinalysis results were correlated with findings on abdominal computed tomography (CT). All patients had more than three red blood cells per high power field (RBC/ hpf) or gross hematuria. Renal injuries were graded according to the injury scale defined by the American Association for the Surgery of Trauma. Sixty-five patients had microscopic hematuria. Thirty-five (54%) were evaluated with an abdominal CT scan. Three patients sustained significant renal injuries (grade II-V), and 32 patients had normal findings or renal contusions. Therefore only 3 of 65 patients (4.6%) sustained a significant renal injury. All three patients had other associated major organ injuries. Of the three patients with gross hematuria evaluated with abdominal CT, one (33%) sustained a significant renal injury and had no associated injuries. The degree of hematuria did not correlate with the grade of renal injury. Pediatric patients with blunt trauma, microscopic hematuria, and no associated injuries do not require radiologic evaluation, as significant renal injuries are unlikely. However, children who present with associated injuries and microscopic hematuria after blunt trauma may have significant renal injuries and should undergo radiologic evaluation.     

Non-operative management of solid organ injuries in children: An American Pediatric Surgical Association Outcomes and Evidence Based Practice Committee systematic review

PurposeThe American Pediatric Surgical Association (APSA) guidelines for the treatment of isolated solid organ injury (SOI) in children were published in 2000 and have been widely adopted. The aim of this systematic review by the APSA Outcomes and Evidence Based Practice Committee was to evaluate the published evidence regarding treatment of solid organ injuries in children.MethodsA comprehensive search strategy was crafted and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were utilized to identify, review, and report salient articles. Four principal questions were examined based upon the previously published consensus APSA guidelines regarding length of stay (LOS), activity level, interventional radiologic procedures, and follow-up imaging. A literature search was performed including multiple databases from 1996 to 2016.ResultsLOS for children with isolated solid organ injuries should be based upon clinical findings and may not be related to grade of injury. Total LOS may be less than recommended by the previously published APSA guidelines. Restricting activity to grade of injury plus two weeks is safe but shorter periods of activity restriction have not been adequately studied. Prophylactic embolization of SOI in stable patients with image-confirmed arterial extravasation is not indicated and should be reserved for patients with evidence of ongoing bleeding. Routine follow-up imaging for asymptomatic, uncomplicated, low-grade injured children with abdominal blunt trauma is not warranted. Limited data are available to support the need for follow-up imaging for high grade injuries.ConclusionBased upon review of the recent literature, we recommend an update to the current APSA guidelines that includes: hospital length of stay based on physiology, shorter activity restrictions may be safe, minimizing post-injury imaging for lower injury grades and embolization only in patients with evidence of ongoing hemorrhage.Type of StudySystematic Review.Levels of EvidenceLevels 2–4.     

Surgeon choice in management of pediatric abdominal trauma

BackgroundNo guidelines exist for management of hemodynamically stable children with suspected hollow viscus injury. We sought to determine factors contributing to surgeon management of these patients.MethodsSurgeon members of the Eastern Association for the Surgery of Trauma and American Pediatric Surgical Association completed a survey on 3 blunt abdominal injury scenarios: (1) isolated, (2) with multisystem injury, and (3) with traumatic brain injury (TBI), and a penetrating injury scenario. Multivariable logistic regression was used to determine factors associated with initial management of observation vs. operation for blunt injury and observation vs. local wound exploration versus laparoscopy for penetrating injury.ResultsOf 394 surgeons (response rate 22.3%), 50.3% were pediatric surgeons. For scenarios 1–3, 32.2%, 49.3%, and 60.7% of surgeons chose operation over observation, respectively. Compared to isolated blunt injury, surgeons were more likely to choose operation for patients with multisystem injury (aOR 2.20, 95%CI: 1.78–2.72) or TBI (aOR 3.60, 95%CI: 2.79–4.66). Pediatric surgeons were less likely to choose operation (aOR 0.32, 95%CI: 0.22–0.44). For penetrating injury, 39.1%, 29.5%, and 31.5% of surgeons chose observation, local wound exploration, and laparoscopy, respectively.ConclusionsLarge variation exists in management of hemodynamically stable children with suspected hollow viscus injury. Although patient injury characteristics account for some variation, surgeon factors such as type of surgeon also play a role. Evidence-based practice guidelines should be developed to standardize care.Type of StudyCross-Sectional Survey.Level of EvidenceN/A     

Significance of minimal or no intraperitoneal fluid visible on CT scan associated with blunt liver and splenic injuries: a multicenter analysis

BACKGROUND: The use of ultrasound (U/S) for the evaluation of patients with blunt abdominal trauma is gaining increasing acceptance. Patients who would have undergone computed tomographic (CT) scan may now be evaluated solely with U/S. Solid organ injuries with minimal or no free fluid may be missed by surgeon sonographers. OBJECTIVE: The purpose of this study was to describe the incidence and clinical importance of liver and splenic injuries with minimal or no free intraperitoneal fluid visible on CT scan. We hypothesized that these solid organ injuries occur infrequently and are of minor clinical significance. METHODS: Patient records and CT scans were reviewed for the presence of and outcome associated with blunt liver and splenic injuries with minimal (<250 mL) or no free fluid detected by an attending radiologist. Data were collected from six major trauma centers during a 4-year period before the introduction of U/S and included demographics, grade of injury (American Association for the Surgery of Trauma scale), need for operative intervention, and outcome. RESULTS: A total of 938 patients with liver and splenic injuries were identified. In this group, 11% of liver injuries and 12% of splenic injuries had no free fluid visible on CT scan and could be missed by diagnostic peritoneal lavage or U/S. Of the 938 patients, 267 (28%) met the inclusion criteria; 161 had injury to the spleen and 125 had injury to the liver. In the 267 patients studied, 97% of the injuries were managed nonoperatively. However, 8 patients (3%) required operative intervention for bleeding. Compared with the liver, the spleen was significantly more likely to bleed (p = 0.01), but the grade of splenic injury was not related to the risk for hemorrhage (p = 0.051). CONCLUSION: Data from this study suggest that injuries to the liver or spleen with minimal or no intraperitoneal fluid visible on CT scan occur more frequently than predicted but usually are of minimal clinical significance. However, patients with splenic injuries may be missed by abdominal U/S. We found a 5% associated risk of bleeding. Therefore, abdominal U/S should not be used as the sole diagnostic modality in all stable patients at risk for blunt abdominal injury.     

Canadian Association of General Surgeons evidence based reviews in surgery. 11. Evidence-based guidelines for children with isolated spleen or liver injury.

Objective: To determine the impact of clinical practice guidelines (CPGs) on the management of trauma to the pediatric spleen and liver. Data sources: The CPGs were formulated by the American Pediatric Surgery Association (APSA) based on evidence from multiple sources including published non-randomized trials, historical controls and expert clinical experience and consensus, along with a retrospective review of 856 children with isolated spleen or liver injuries treated at 32 centres of pediatric surgery from June 1995 to July 1997. CPG implementation: The CPGs were applied prospectively in 312 children treated nonoperatively at 16 centres between 1998 and 2000. Compliance was analyzed for age, gender, the organ injured and its grade by computed tomography. All patients underwent follow-up for 4 months. Outcomes: Hospital stay, follow-up imaging and interval of activity restriction. Main results: Compared with the 832 patients previously studied, the 312 patients who had prospective application of the proposed guidelines had significant reductions in intensive-care-unit (ICU) and hospital stay (both p < 0.0006), follow-up imaging (p < 0.0001) and interval of rest from physical activity (p < 0.05) at each grade of injury. Conclusion: Application of specific CPGs based on injury severity has resulted in conformity in patient management, improved utilization of resources and validation of guideline safety.     

Sports participation and high grade renal injuries in children

PURPOSE: The risk of major renal injury resulting from various forms of sports participation is unknown. Urologists often recommend that children with a solitary kidney avoid contact sports. We reviewed our recent experience with pediatric renal trauma to determine if there is an association between different types of sports activity and high grade renal injury. MATERIALS AND METHODS: We retrospectively reviewed the medical records of 68 consecutive children with blunt renal injury who were treated at 2 level I trauma centers. Injuries were graded using the renal injury scale of the American Association for the Surgery of Trauma. Records were reviewed for mechanism of injury, associated injuries, management and injury severity score. Statistical analysis was performed using Fisher's exact test or Wilcoxon rank sum test. RESULTS: Of the 68 renal lesions 13 were grade I, 15 grade II, 15 grade III, 17 grade IV and 8 grade V. The most common cause of renal trauma was motor vehicle accidents, accounting for 21 injuries (30.1%). Accidents associated with nonmotorized sports activity accounted for 14 injuries (20.6%). Bicycle riding was the most common sports etiology, accounting for 8 of 14 cases (57.1%) at an age range of 5 to 15 years (mean 9.4). None of the bicycle injuries involved collision with a motor vehicle. Bicycling accounted for 1 grade I, 1 grade II, 1 grade III, 2 grade IV and 3 grade V injuries. Football, hockey and sledding were responsible for the remaining 6 sports related injuries. High grade renal injury (grade IV or V) was identified in 5 of 8 bicycle accidents (62.5%) and 1 of 6 nonbicycle sports related injuries (16.7%, p = 0.14). Injury severity scores ranged from 4 to 50 (mean 20.6) for bicycle renal injuries and 4 to 13 (mean 6.7) for nonbicycle sports related trauma (p <0.05). Parents indicated that blunt trauma from the handlebars was the major factor contributing to renal injury in 3 bicycle cases. Renal trauma from bicycle riding resulted in 1 nephrectomy. CONCLUSIONS: Bicycle riding is the most common sports related cause of renal injury in children and is associated with a significant risk of major renal injury. Families of children with a solitary kidney should be aware of this risk factor. Team contact sports are an uncommon cause of high grade renal injury. Current recommendations regarding sports participation by children with a solitary kidney need to be reevaluated.     

Comparison between level 1 and level 2 trauma centers for the management of splenic blunt trauma

IntroductionThe management of blunt splenic trauma has evolved in the last years, from mainly operative approach to the non-operative management (NOM). The aim of this study is to investigate whether trauma center (TC) designation (level 1 and level 2) affects blunt splenic trauma management.MethodsA retrospective analysis of blunt trauma patients with splenic injury admitted to 2 Italian TCs, Niguarda (level 1) and San Carlo Borromeo (level 2), was performed, receiving either NOM or emergency surgical treatment, from January 1, 2015 to December 31, 2020. Univariate comparison was performed between the two centers, and multivariate analysis was carried out to find predictive factors associated with NOM and splenectomy.Results181 patients were included in the study, 134 from level 1 and 47 from level 2 TCs. The splenectomy/emergency laparotomy ratio was inferior at level 1 TC for high-grade splenic injuries (30.8% for level 1 and 100% for level 2), whose patients presented higher incidence of other injuries. Splenic NOM failure was registered in only one case (3.3%). At multivariate analysis, systolic pressure, spleen organ injury scale (OIS) and injury severity score (ISS) resulted significant predictive factors for NOM, and only spleen OIS was predictive factor for splenectomy (Odds Ratio 0.14, 0.04–0.49 CI 95%, P < .01).ConclusionBoth level 1 and 2 trauma centers demonstrated application of NOM with a high rate of success with some management difference in the treatment and outcome of patients with splenic injuries between the two types of TCs.     

Nonoperative management of blunt hepatic and splenic injury in children.

OBJECTIVE: The authors assessed the risks of nonoperative management of solid visceral injuries in children (age range, 4 months-14 years) who were consecutively admitted to a level I pediatric trauma center during a 6-year period ending in 1991. METHOD: One hundred seventy-nine children (5.0%) sustained injury to the liver or spleen. Nineteen children (11.2%) died. Of the 160 children who survived, 4 received emergency laparotomies; 156 underwent diagnostic computer tomography and were managed nonoperatively. The percentage of children who were successfully treated nonoperatively was 97.4%. Delayed diagnosis of enteric perforations occurred in two children. Fifty-three children (34.0%) received transfusions (mean volume 16.7 mL/kg); however, transfusion rates during the latter half of the study decreased from 50% to 19% in children with hepatic injuries, despite increasing grade of injury, and decreased from 57% to 23% in the splenic group with similar injury grade (p < 0.005, chi square test and Student's t test). CONCLUSION: Pediatric blunt hepatic and splenic trauma is associated with significant mortality. Nonoperative management based on physiologic parameters, rather than on computed tomography grading of organ injury, was highly successful, with few missed injuries and a low transfusion rate.     

Adrenal injuries following blunt abdominal trauma in children: report of two cases

Adrenal injuries following blunt abdominal trauma are uncommon. Adrenal hemorrhage in children associated with multiple organ injury, which has received little attention in the past, is an increasingly recognized phenomenon in modern trauma centers with the widespread use of abdominal computed tomography. Adrenal trauma occurs in the setting of multisystem organ injury. Isolated adrenal injury is exceedingly rare. We report two children with blunt adrenal trauma (one isolated and one with associated injuries), who were admitted during the last two years to our Pediatric Surgery Department after abdominal trauma. We determined the prevalence, management and general prognosis of blunt adrenal injury in the pediatric population. Traumatic adrenal hemorrhage appears to be an incidental and unsuspected finding that resolves on follow-up imaging.     

Blunt renal trauma in children: experience with conservative management at a pediatric trauma center

BACKGROUND: The authors reviewed the outcome for children with blunt renal injury managed with a nonoperative protocol at their pediatric trauma center. METHODS: Fifty-five consecutive children aged 0.5 to 17 years with blunt renal injury managed over a 14-year period were reviewed. All patients were evaluated with computed tomographic scanning. Injuries were graded according to the American Association for the Surgery of Trauma Organ Injury Scale. RESULTS: Forty-eight of 55 children (87%) were successfully managed nonoperatively. Overall, there were 5 grade I, 13 grade II, 18 grade III, 14 grade IV, and 5 grade V injuries. All children with grades I and III injuries were successfully managed nonoperatively. Two (6%) of these children required transfusion. Only four (29%) children with grade IV and three (60%) with grade V injuries required surgical interventions (one nephrostomy, six nephrectomies). Excluding patients with continuing hemorrhage, only 2 (14%) of 14 with high-grade injuries required surgical intervention (1 nephrostomy, 1 nephrectomy). Clearance of gross hematuria correlated with severity of injury and was prolonged in grade IV and V compared with grade I to III injuries (6.8 +/- 2.7 vs. 3.2 +/- 2.1 days, respectively; p < 0.05). Fifty-one children (93%) available for follow-up were normotensive with normal renal function. CONCLUSION: These data support the use of conservative management for all grades in stable children with blunt renal injury. Transfusion requirements, operative rates, and outcome are consistent with other pediatric solid organ injuries.     

Management of pediatric splenic injuries in Canada

PurposeNonoperative management (NOM) of blunt splenic injuries has become the standard of care in hemodynamically stable children. This study compares the management of these injuries between pediatric and nonpediatric hospitals in Canada.MethodsData were obtained from the Canadian Institute of Health Information trauma database on all patients aged 2 to 16 years, admitted to a Canadian hospital with a diagnosis of splenic injury between May 2002 and April 2004. Variables included age, sex, associated major injuries, splenic procedures, intensive care unit (ICU) admissions, blood transfusions, and length of stay. Hospitals were coded as pediatric or nonpediatric. Univariate analysis and logistic regression were used to determine associations between hospital type and outcomes.ResultsOf 1284 cases, 654 were managed at pediatric hospitals and 630 at nonpediatric centers. Patients at pediatric centers tended to be younger and more likely to have associated major injuries. Controlling for covariates, including associated major injuries, patients managed at pediatric centers were less likely to undergo splenectomy compared with those managed at nonpediatric centers (odds ratio [OR], 0.2; 95% confidence interval, 0.1-0.4). The risk of receiving blood products, admission to the ICU, and staying in hospital for more than 5 days was associated only with having associated major injuries.ConclusionEven in the presence of other major injuries, successful NOM of blunt splenic injuries occurs more frequently in pediatric hospitals in Canada. This has policy relevance regarding education of adult surgeons about the appropriateness of NOM in children and developing guidelines on appropriate regional triaging of pediatric patients with splenic injury in Canada.
